Design Checklist

3.21.1Design Considerations

•The Intel® Pentium® II processor retention mechanism, retention mechanism attach mount and heat sink support is an optional support structure for retaining the Slot 1 processor in the system during shock and vibration situations. If these Intel enabled retention solutions are

used, the motherboard keep out zones and mounting hole requirements must be met. See the Intel® Pentium® II Datasheet for details.

•The Boxed Intel® Pentium® II processor requires the implementation of the heatsink support holes for the heatsink support structure as defined in the Intel® Pentium® II Datasheet to properly support the Boxed Intel® Pentium® II processor fan/heatsink.

•It is recommended that simulations be performed on the GTL+ bus to ensure that proper bus timings and signal integrity are met, especially if the layout guideline recommendations in this document are not followed.

•It is recommended that simulations be performed to ensure proper timings and signal integrity is met, especially if the non GTL+ (CMOS) layout guideline recommendations in this document are not followed.

•Verify the voltage range and tolerance of your VRM or onboard regulator adequately cover the VccCORE requirements of the Slot 1 processor(s) is supported.

•Verify the maximum current value your VRM or on board regulator can support at VccCORE. This should meet the value specified by the VRM 8.2 DC-DC Converter Specification.

•Verify the voltage tolerance of your VRM or on board regulator at VccCORE. This should meet the value specified by the VRM 8.2 DC-DC Converter Specification.

•Adequate 5V and/or 3.3V decoupling should be provided for all components.

•VREF for the AGPset should be decoupled to VTT with 0.001mF capacitors at each voltage divider. It should be decoupled to ground, to ensure an even better solution.

•It is recommended that AC/DC analysis be performed to determine proper pull-up and pull- down values.

440GX specifications

The Intel 440GX chipset was launched in 1997 as part of Intel's series of chipsets known as the 440 family, and it served as a critical component for various Pentium II and Pentium III-based motherboard architectures. Specifically designed for the second generation of Intel’s processors, the 440GX delivered enhanced performance and supported a range of important technologies that defined PC architectures of its time.

One of the main features of the Intel 440GX was its support for a 100 MHz front-side bus (FSB), which significantly improved data transfer rates between the CPU and the memory subsystem. This advancement allowed the 440GX to accommodate both the original Pentium II processors as well as the later Pentium III chips, providing compatibility and flexibility for system builders and consumers alike.

The 440GX chipset included an integrated AGP (Accelerated Graphics Port) controller, which supported AGP 2x speeds. This enabled high-performance graphics cards to be utilized effectively, delivering many enhanced graphics capabilities for gaming and multimedia applications. The AGP interface was crucial at the time as it offered a dedicated pathway for graphics data, increasing bandwidth compared to traditional PCI slots.

In terms of memory support, the 440GX could address up to 512 MB of SDRAM, allowing systems built with this chipset to run comfortably with sufficient memory for the era’s demanding applications. The memory controller was capable of supporting both single and double-sided DIMMs, which provided versatility in memory configuration for system builders.

Another notable feature of the Intel 440GX was its support for multi-processor configurations through its Dual Processors support feature. This allowed enterprise and workstation computers to leverage the performance advantages of multiple CPUs, making the chipset suitable for business and professional environments where multitasking and high-performance computing were essential.

On the connectivity front, the chipset supported up to six PCI slots, enhancing peripheral device integration and expansion capabilities. It also included integrated IDE controllers, facilitating connections for hard drives and CD-ROM devices.

Overall, the Intel 440GX chipset represented a balanced combination of performance, flexibility, and technology advancements for its time. Its introduction helped establish a foundation for subsequent advancements in PC technology and set the stage for more powerful computing systems in the years to come.
